STENCIL APPARATUS.

SPECIFICATION forming part of' Letters Patent No. 495,604, dated April18, 1893.

Application led Juno 6, 1892. Serial No. 435,768. (No model.)

To a/ZZ whom it may concern:

Be it known that I, HENRY SORG, of Rochester, in the county of Monroeand State of New York, have invented a certain new and usefulImprovement in Stencil Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the drawings accompanying this specification.

Myimprovement relates to stenciling apparatus and consists in theconstruction and arrangement of parts hereinfter described and claimed.

Inv the drawing--Figure l is a plan View of the apparatus. Fig.2 is alongitudinalvertical section in line @c of Fig. l. Fig. 3 is a plan viewof one end of the flexible stencil ribbon and a portion of the guidewith which it connects. Fig. 4 is a cross section of the ribbon and anelevation of the inking roller.

A indicates the frame, consisting of two side bars a a and a rear crossbar b.

c is a handle by which the device is held and operated.

My improvement is as follows:

B and B are two rollers, one in front of another, mounted on xed shaftsd d between the sides a a of the frame. l

ff are spiral springs resting inside the rollers and around the shafts,one end of each being attached to the roller and the other to the shaft.By this means spring action is imparted to the roller sufcientto wind upthe stencil ribbon.

C C are the stencil ribbons or bands, one for each roller. Theyareattached to the rollers and wound up thereon. They are cut witha Seriesof letters,figures, or other desired characters, andwhen the device isin use are brought under the inking roller by simply drawing the ribbonoutward against the tension of the spring roller. I do not limit myinvention to any particular number of spring rollers and ribbons.Forordinary purposes a single roller and ribbon are sufficient. Wheretwo ribbons are used one preferably has letters and the other iigures. A

D is a guide, consisting of a wire loop or stirrup fastened at one endto the frame, the other end extending forward angularly as shown, andthe free ends of the ribbons running through the same.

The ends of the ribbons have rods g g, which project su liicientlybeyond the sides of the guides to preventthe ribbons from being drawnback free of the guides. This is shown in Fig. 3. On the back of theguide are stops 7L h, to prevent the ribbons from slipping down out ofplace when not in use. On the edges of the ribbons are narrow flexiblestrips 7c lc, of rubber or other suitable material,which will wind withthe ribbons, said strips serving as dams to prevent the ink from fiowingolf at the sides. Small pins Z Z may also be placed at the sides,opposite the characters on the ribbon, to indicate their position whendrawn out for use.

E is the ink well, mounted in a suit-able position on the frame, its tophaving a lling cap fm, and its bottom a slot or opening through whichthe ink can pass. G is a transferring roller under the well, and H isthe in king roller for applying inkto the ribbon. The two rollers arealways in contact, and are geared together by spur gears n n at `oneend. The bottorn of the ink well is protected by a felt or other packingo, which prevents leakage.. The felt may be dispensed with.

In use the apparatus is placed over the surface to be marked and theribbon is drawn out till the desired letter rests under the inkingroller. The latter is then rolled overit till the print is made. Theapparatus is then shifted sidewise to the position for the secondletter, the ribbon is drawn out to bring the second letter under theinking roller, and this process is repeated till the desired word isprinted. When the ribbon is released the spring roller draws it back toplace. The ribbon is preferably made of thin and flexible sheet metal,but may be made of any other suitable material. The inking roller alsohas preferably a composition similar to that used on printers rollers,but any suitable substitute may be used. A

Having described my invention, I do not claim a set of rollers with anendless stencil band passing between them.

What I claim as new, and desire to secure by Letters Patent, is

l. In a stencil apparatus, the combination, with the frame A, of theinking apparatus consisting of the iuking roller H, transferring rollerG and well E, mountedon the rear of the frame, the spring roller B,mounted on the front of the frame, and the stencil ribbon C attached tothe roller and winding thereon by its spring action, as shown anddescribed and for the purpose specified.

2. In a stencil apparatus, the combination, with the inking apparatusconsisting of the ink roller H, transferring roller G and Well E, andWith the stencil apparatus consisting of the spring roilerB and ribbonC, of the guide lo D, consisting of a loop, arranged angularly betweensaid parts and provided with a stop 7L for holding the free end of theribbon, as herein shown and described.

In witness whereof I have hereunto signed my naine in the presence oftwo subscribing r 5 witnesses.
